ALININ'G APPARATUS FOR PRINTERS FORMS.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed July 3, 1916. Serial No. 107,217.

To all whom it may concern:

Be it known that I, FREDERICK A. PooLn, a citizen of the United States,residing at Chicago, in the county of Cookand State of Illinois, haveinvented certain new and useful Improvements in Alining Apparatus forPrinters Forms, of which the following is a specification.

My invention relates to improvements in alining apparatus for printersforms and relates more particularly to that class of apparatus of whichthe device shown in United States patent to Rowse No. 1,133,822, issuedMarch 30, 1915, is an example.

The object of my invention is to provide an apparatus of the classdescribed, so organized that the locking of a number of page forms intoa sheet form layout may be accomplished rapidly, accurately, and withoutthe necessity of troublesome mechanical manipulations or mathematicalcalculations; to provide an arrangement of the class described, theconstruct-ion of which is such that it will accommodate all sizes ofpages having any desired widths of margin with out the necessity ofsubstituting or changing parts of the apparatus or using different sizedappliances; to provide a construction which is simple and economical tomanufacture; and, in general, to provide an improved construction of thecharacter referred to.

In the drawings which illustrate a preferred embodiment of my inventionFigure 1 is a .plan view of a lock-up stone equipped with myimprovements;

Fig. '8 is a'fraginentary side elevationof Fig.

Referring to the drawings, 10 represents the lock-up stone or imposingplate which forms'a bedortable upon which the alining and registering ofthe forms is carried out. Said lock-up stone is a substantial cast ironrectangular slab suitably supported'at a convenient height, forinstance, upon a printers cabinet, and planed off smooth on its uppersurface. The chase in which the page forms are to be locked up toconstitute a sheet form is indicated at 11 and the page forms (in thepresent case sixteen in number to form a sixteen-page book) areindicated at 12 to 27, inclusive. In the drawing I have shown the pageforms locked up in the chase, but of course it should be understood thatsaid forms are not finally locked up in the chase until the aliningapparatus has been utilized to accurately position the page forms.

Around three sides of the plate are permanently secured by cap screws orother devices three flat bars 28, 29 and 30 which project above thesurface of the lock-up stone, as shown in Fig. 2. On the right-hand sideof the plate there is also detachably mounted a similar flat bar 31which may be removed from the stone by slacking off the cap screws 32,33, 34 and 35, thereby enabling the bar 31 to be lifted verticallyupward and removed bodily. The devices which constitute the importantpart of my invention are carried on the upwardly projecting portions ofthe bars 28, 29, 30 and 31. 36 represents a longitudinal mounting blockmade of machine steel or other suitable metal, in the under side ofwhich is cut a groove 37 which fits over the upper edge of one of theedge bars 28, 29, 30 or 31. Midway of the length of the block a threadedhole accommodates a set screw 38 with a milled head 39 by which theposition of the mounting block 36 along the edge bar may be adjusted andheld. In the upper face of the mounting block is out a rectangulargroove 40 the ends of which are closed, the top of the groove being opento accommodate the sliding alining guides or gages 41 and 42. Said gages41 and 42 are rectangular in order to fit and slide in the groove 40. Asshown in Fig. 6, the upper ends of thegages 41 and 42 project above thelevel of the top of the mounting block 36 and are inclined downwardlytoward the lock-up stone and are provided with saw cuts 43 in order toaccommodate alining strings, as shown at 44.

The gage blocks 41 and 42 are tapped respectively with a left-hand andaright-hand thread'in order to accommodatecorrespondin'g left-handthreads 45 and right-hand threads/46 on a micrometer screw 47. As shownbest in Fig. 4, said micrometer screw is reduced at its right-hand endto form a of the screw for adjusting purposes is accomplished by meansof the knurled head 52 which is secured upon the extended end of thestem50 by means of a diametric pin 53. Improper movements of the adjustingscrew are largely prevented by means of a conical headed pin 54 arrangedto slide in a short cylindrical bore 55 under the influence of a coilspring 56 which forces the conical head 57 of the pin 54 into one orother of a pair of diametrically opposed conical recesses orcountersinks 58 in the end of the mounting block 36. It will of coursebe readily understood by those skilled in the art that the mountingblock 36 must be made in two or more parts in order to permit theinsertion of the micrometer screw, although it is unnecessary todescribe such sectional construe tion in detail. 7 7

Each of the gage block mountings 36 is provided on its upper surfacewith a scale 59, preferably in inches and sixteenths, the zero point ofwhich coincides with the center of a gage hole 60 positioned centrallybetween the said kerfs 43 and gage blocks 41' and 42. Such symmetricalrelation ofthe blocks 41 and 42 with reference to the gage hole 60isalways maintained by reason of the fact that the threads 45 and 46 havethe same pitch, each of the blocks therefore moving an equal amount toor from the center when the milled collar 52 is turned. 7 a

In using the apparatus, the page forms are roughly placed in position onthe lock-up stone, the bar 31. is applied, and a pair of strings arestretched across the permanent orend gage blocks 61, 62, 63 and 64.These end gages 61, 62, 63'and 64 are single-ended since theyaccommodate only one string and are so'positioned that the strings 65and 66 cross each other exactly at right angles when the gage blocks onsaid end mountings are properly adjusted. Scales are marked on the endblocks 61, 62, 63 and 64 similar to the scales 59 on the'double gagemountings, gage holes being also drilled at the zero points of saidscales.

In setting the strings65 and 66the operator, by means of the micrometerscrews, adjusts the gage blocksin. such position that the strlngs'or sawcutsin the gage blocks willjbe located at distances from the gage holescorresponding to the allowance'to be made for margin and trimmingbetween the edge of the paper and the boundary of the printing area.Having properly adjusted the gages 61, 62, 63 and- 64 for the strings 65and 66, the operator sets the gage bar 67, Fig. 7, to the properdistance between the edge of the sheet which is to be printed and thepoint where the first fold of said sheet is to be located. Saidadjustment of the gage bar 67 is eflected by means of a sliding clamp 68which may be set by a knurl screw 69'according to a scale 70. The fixedgage pin 71 is then inserted in the end block 64 and the properlyadjusted slidable gage pin 72 is inserted in the mounting 36 by sliding.the latter along the edge bar 29 until it is in such position as'topermit the entrance of said gage pin 72. The thumb screw 38 is thenturned to clamp the mounting 36 securely in position on said bar. Theother gage block mountings on the side edges of the plates are similarlyclamped in position, after which the adjustment of the gage bar is chaned to correspondwith the width instead 0% the length of the page, afterwhich the end gage block mountings are clamped in position. Having thus.utilized .the gage bar 67 to set the gage block mountings around allfoursides of the lockup frame, strings are stretched in the kerfs.

page formsto be locked up into proper. reg1stering position, as shown.

In View of the foregoing, it will be seen that my construction is ofgreat benefit and advantage to the practical printer in en ablinghim tolock up a large .number of page forms in each chase with a minimum oftrouble or opportunity for mistakes. Provided that the preliminarylocation of the gage block mountings has been properly effected, whichis an easy matter with the gage bar, the only thing then necessary is toadjust all of the micrometric' mountings an equal amount. With myimproved -micrometric gages there is no possible opportunity for lockingthe gage strings at different distances from the fold in the paper,

assuming ofcourse that the printer has properly calculated the distancebetween folds and has set hisgage bar accordingly.

The manipulation of the apparatus will be to use in connection withlock-up stones, but

may conceivably be'used in connectio'nwith other devices or apparatus bymeans of which the page forms" are locked up into a sheet form. The termlock-up frame as used in the claims is intended to cover all devicesdesigned for the general purpose of a lock-up stone as used inconnection with a chase. I consider within the scope of my invention anyarrangement by which the gage-string supports are properly coordinatedwith the chase or holder for the forms. Such lock-up frame on which thegagestring supports are founded need not necessarily include the lock-upstone as ordinarily employed.v

The described details of construction merely illustrate the applicationof my invention, the scope of which must be determined by reference tothe appended claims.
